These places are closed by a casing of a gear belt Sealing linings of a cover of a head of the block of cylinders. Sealing lining of a head of the block of cylinders. Sealing lining of the distributor of ignition (model with 4 and 5-cylinder engines). Switches with a hydrodrive. Sealing lining of the oil filter.
